Research Status of Synthetic Oil Well Cement Retarder
View through CrossRef
Background:
Oil well cement retarder is an additive that can extend time for thickening
cement slurry, which can ensure the safety of cement. At present, the oil well cement retarder is
mainly composed of synthetic materials, which are mainly divided into three major categories:
compound polymer, AMPS polymer and non-AMPS.
Methods:
In this paper, the research status of synthetic oil well cement retarder in recent years is
reviewed, and its shortcomings and development trends are analyzed. It is pointed out that the shortage
of synthetic retarder mainly lies in problems, including large temperature sensitivity, small temperature
application range, abnormal thickening curve, great influence on high temperature settlement
stability and cement stone strength development.
Conclusion:
The development direction of oil well cement retarder is mainly focused on developing
intelligent retarder and degradable retarder to meet the cementing needs of oilfields and ensure cementing
effect increasing steadily.
